The
following link will take you to a site that lists the known
congenital and heritable disorders in different breeds. First you
scroll down to the breed you are interested in. Jot down each of
the numbers that follows that breed. Then scroll down to the bottom
of the list. Look up each number to see what congenital or
heritable disorder it signifies.

This site also has a
page on fly-biting or fly catcher's syndrome as well as a small
video depicting a dog fly-biting. Click on Canine Epilepsy Basics.
Scroll down that page to Complex Focal Seizures to find a link to
this page. Fly-catchers is thought of as a possible type of seizure
or some specialists think it may be a type of OCD--obsessive
compulsive disorder. However there is thought that some types of
OCD may also be some type of strange seizure disorder. Since both
are neurological in nature, both thoughts could be correct.

Some
Cavalier lines are prone to early onset deafness--either partial or
total. There is a test for this that is slowly becoming more
available, but at the moment is not readily available. Cavaliers
who have developed early onset deafness should not be bred.

BACK
PROBLEMS

Cavaliers can be affected by back problems, i.e ruptured disks, the
same way a human can. Cavaliers who develop this problem early
should not be bred. For more on disk disease please see the
following site:

Autoimmune disorders are many. Allergies, cancer, myasenthia
gravis, demodectic mange and lupus are all autoimmune disorders.
Cavaliers who develop any type of autoimmune disorder, should not be
bred. For more on autoimmune disorders, please see the following
